Question

Calculate the mass of 0.72gm molecules of Co2 (Atomic mass of carbon = 12 units and oxygen = 16 units

Answer 1

The answer is 31.68 units

hope it helps!!!

Answer 2

Answer:

Gram molecular mass of CO2 = 44 g

i.e. 1 g molecule of CO2 has mass = 44 g

So, 0.72 g molecule of CO2 will have mass = 44 x 0.72 g

= 31.68 g
